Inficon Quadrex 100 017-010-G1 Residual Gas Analyzer 100 AMU RGA For Parts

Inficon Quadrex 100 017-010-G1 Residual Gas Analyzer 100 AMU RGA For Parts

The Inficon Quadrex 100 is a benchtop quadrupole residual gas analyzer (RGA) designed to detect and measure trace gases in vacuum systems by scanning a mass range of 1 to 100 atomic mass units (AMU). It features a built-in CRT display with five selectable data display formats and on-board memory for storing up to four displays. This unit (model 017-010-G1) powers on, but the CRT produces either a blank screen or scrambled text, indicating a failing display. It is being sold as-is for parts or repair.

Applications

Residual gas analyzers like the Inficon Quadrex 100 are used in vacuum process environments to identify and monitor the partial pressures of gas species present inside a vacuum chamber. They are standard diagnostic tools in semiconductor fabrication, thin-film deposition (PVD/CVD), electron beam systems, surface science research, and mass spectrometry laboratories. The Quadrex 100 was part of Inficon's (then operating as Leybold-Heraeus) line of integrated RGA systems from the 1980s and early 1990s, distinguished by their all-in-one benchtop design with a self-contained CRT display and dedicated keypad — a contrast to later PC-based RGA systems that offloaded the display to a host computer. A working Quadrex 100 is still sought by vacuum system operators maintaining legacy deposition or etch tools, as well as by researchers and technicians who need a standalone RGA without a PC interface. This unit, with its failing CRT, is well suited for parts harvesting, CRT replacement/repair, or integration with an external video monitor via the rear VIDEO connector.
